INSULATOR ATTACHMENT.

Specification of Letters Patent.

Patented July 31, 1917.

Application filed January 24, 1917. Serial No. 144,143.

To all whom it may concern:

Be it known that I, ADELBERT G. BURNETT, citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Insulator Attachments, of which the following is a specification.

My invention relates to insulator attachments, and is designed more specifically to provide a method of securing high tension wires to the insulator in such manner that the wire may be detached from the insulator, for the purpose of renewing theinsulator, or any other desirable purpose, without first turning the current off of the wire, and also to provide a non-rigid, flexible attachment for holding the wire to the insulator.

It is well known that where the current wire is secured to the insulator by tie-wires, or other usual methods, the workman must, before detaching the Wire from the insulator for any purpose whatsoever, have the current turned ofl between the switching structures or stations, where parallel lines are used, and in case of single lines, often the entire length of the line.

It is also a fact that winds have a great deal of effect upon wires, and where these wires are rigidly attached to the insulators there is great tendency to breakage, which will be very materially reduced by the use of flexible, yielding attachments.

Another advantage of my device is that it renders it entirely practical to take up all slack in the wire without first detaching the wire from the insulator.

For the purpose of illustration, I have used what is commonly known as the petticoat type of high tension insulator, and in the drawings, Figure 1 is a side elevation; Fig. 2 is a sectional view on line 22 Fig. 1 and looking at right angles thereto; Fig. 3 is a perspective view of the attaching stirrup or saddle; and Fig. 4. is a detail view of the anchor post, with the retaining bar turned into alinement therewith for the purpose of mounting or removing the saddle.

In the construction of my device the anchor post 6, of any suitable material, is preferably cast or molded into the body of the insulator, as plainly shown in Fig. 2. It is obvious, however, that this post may be secured to the insulator in any one of numerous ways without departing from scope of my invention.

A portion of the outer end of this post is cut away as at 70 to provide a space for the holding or retaining bar (Z, which is pivoted to the remaining portion of the outer end of the post as at h, and carries the stop pin 2'. The saddle or stirrup 0 is provided with the opening Z, and while the retaining bar d is in alinement with the anchor post I) the saddle may be slipped on to the post, after which the bar cl is turned at right angles to the post, as shown in Fig. 1, which will prevent the saddle c from being lifted off of the post. The wire f is then placed in the loop of the saddle and the thumb screw 6 turned up.

When it is desired to change an insulator the workmen will simply have to turn the holding bar cZ into alinement with the post 6, and with a stick, or other non-conductive material, lift the saddle 01f the post, slide it along the wire, put on a new insulator and reassemble as before. The pin 2' is so disposed that it will engage the flaring end 7' of post 6 at a point to stop it in alinement with the post.

When it is desired to take up slack in the wire, the workman simply loosens the thumb screw which holds the wire in the loop of the stirrup, when the wire may be drawn tight without difficulty.

While my device is designed primarily for the purpose above suggested, it may also be used in turning corners, and at terminals, or dead-ends, in place of the figure 8, so called.

I claim: I

1. In combination with an insulator, a post carried by the insulator, a bar pivotally attached to said post, and a wire-carrying stirrup detachably engaging said post.

2. In combination with an insulator, a post carried by the insulator, a swinging bar carried by said post, and a wire-carrying stirrup detachably engaging said post.

3. In combination with an insulator, a post cast into the insulator, a bar pivotally attached to said post, and a wire-carrying saddle detachably engaging said post.

4. In combination with an insulator, a post cast into the insulator, a swinging bar carried by said post, and a wire-carrying stirrup detachably engaging said post.

5. In combination with an insulator, a

post carried by the insulator,said post having a portion of its outer end cut away, a bar pivotally attached to said post and occupying the space formed bycutting away a portion of the post, and a wire-carrying stirrup detachably engaging said post.

6. In combination with an insulator, a post carried by the insulator, a bar pivotally attached to said post, and a wire-carrying stirrup detachably engaging said post, said stirrup consisting of a plate of suitable material doubled on itself at one end to form a holding loop, and provided at its other end with a hole to engage said post.

7 In combination with an insulator, a post carried by the insulator, said post having a portion of its outer end cut away, a bar pivotally attached to said post and occupying the space formed by cutting away a portion of the post, and a wire carrying stirrup detachably engaging said post, said stirrup consisting of a plate of suitable material doubled on itself at one end to form a holding loop, and provided at its other end with a hole to engage said post.

In testimony whereof I hereunto aifix my signature in the presence of two Witnesses.
